I seem to have found a work around. If I open the player with the touchpad and bring out the remote first, I am able to use the touch screen to change channels on the remote (then I can go into full screen mode and tap the screen to bring the remote up again). I still can't change channels using the arrows near the streaming bar or control much of anything else, though. I am using a Asus and wonder if it might be a compatibility issue. The touch screen is fine for everything else and has no problems with responsiveness except for with slingplayer.
